Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536388, here are decompositions:

5 + 31536383 = 31536388
29 + 31536359 = 31536388
41 + 31536347 = 31536388
101 + 31536287 = 31536388
227 + 31536161 = 31536388
449 + 31535939 = 31536388
479 + 31535909 = 31536388
509 + 31535879 = 31536388

Showing the first eight; more decompositions exist.
